262: add BinaryHeap::into_vec r=japaric a=Lambda-Logan

std::collections::BinaryHeap provides an into_vec method https://doc.rust-lang.org/std/collections/struct.BinaryHeap.html#method.into_vec

My use case is I want a sorted iterator  similar to BinaryHeap.into_sorted_iter. I found my self creating a new heapless:Vec from heapless::BinaryHeap::into_iter and then sorting it. It seemed better to return the underlying vec and sort that.

But the functionality seemed generally useful and helps the API jive a little better with std::collections::BinaryHeap.

Do you see any issues with this implementation? Also, apologies for anything weird... This is my first PR :)
